Spreadsheet calculations

I want to purchase stock contracts or stocks and calculate my win/losses with a percentile according the number of contracts. Example the purchase of 2 contracts at 1.85 is $185.00 multiplied by 2= $370 invested amount. I'd like to have the return amount based on the exit price for this case it as 1.96 $(196.00). The return amount is $22.00 and Profit/Loss (P/L) is 5.95%.
